Aurelia":374o0h4a said:If we were not always constrained by time, we would cruise at precisely 4.8 knots in our 19. We do travel at this speed for short periods and enjoy the quiet and calm but steady pace. But.... our goals are always stretching our schedule for now so we settle in at 16 knots at 4800rpm much of the time. With a really heavy load that may be closer to 12 knots just to keep the rpms below 5k.

That is with a Carbed Honda 75 and 13 3/4 x 13" 4 blade aluminum prop. We also have a similar prop the is 15" pitch but it doesn't deal with our heavier loads quite as effortlessly
